T 0 all wiz-0m t may concern.'

Be it known that we, VILLIAM il. Sr- Aions and LAURENCE M. KLannnn,citizens ot' the United States, residing' in 'the city ot' New York,State of New York, and in the city of San Diego, county of San Diego,California, respectively, have invented new and use'liul Improvements inRemote-Controlled Switches for High-Tension Trans mission-Lines, oit'which the following is specification. y

This invention relates to switches, and it is especially applicable tothe switches employed on high-tension transmission lines..

The general object i the invention is to provide simple means foreffecting the opening and closing ot the switch `trom a distance. Toaccomplish this we provide a. very simple motive torce for moving theswitch, which will effect the movement of the switch, and which willcooperate with simple and reliable means for positively controlling theoperation of this motive 'orce from a distance.

The invention consists in the novel features, and inthe generalcombination of parts to be particularly described herein after, all ofwhich contribute to produce a simple and eiiicient remote-controlledswitch for high-tension transmission lines. I A preerred embodiment otour invention will be particularly described in the Vfollowingspecification, while thebroad scopeot ourpointed out in the appendjinvention will be ed claims.

In the drawing, c Figure 1 is Va vertical section' through an apparatusembodying our invention, the switch proper, however, being indicateddiagrammatically; and

Fig. 2 is a fragmentary view further illustrating the mode of operationof the apparatus. y Y The controllingparts of the apparatus are mostconveniently housed withina bor` l, which, it desired, may have a lid 2,hinge at 3, so as to give access to the interior or" the box. This boXmay be attached to the side of a'pole Il, carryinga transmission line orlines indicated by the conductors 5 and 6, between which there islocated the switch which may include amovable switch-member or lever 7,the pivot 8 whereof being connected with the line-wire 6, the other endot the lever cooperating with a contact 9 connected with the line-wireWe provide a rotatable member which may consist or a simple wheel 10rotatably mounted on the side of the box 1, and this member connected bysuitable means with the lever 7, in such a way that when the ro--tat-able member or wheel l0 rotates, it will hold the switchalternately open and closed. The means illustrated for connecting thewheel and the switch lever, consists oi a link 11 which is pivotallyattached to the switchlever 7, and similarly attached by a pivotconnection 12 to the wheel. i

ille provide Vmeans tending to rotate this rotatable member or wheel andwe also provide means for holding the wheel in two positions, in one ofwhich, as illustrated in Fig. 1, the pivot connection 12, is disposedadiacent to the switch-lever; the other position of the wheel issubstantially diametricallv opposite to that illustrated, in which casethe pivot connection 12 would lie remote from the switch. y

AAmy suitable means may be provided which will tend to rotate the wheel.This may consist simply of a cable or chain 13 which passes around theperiphery of the wheel, it being understood that the wheel is held in avertical plane. On this chain we provide a detachable weight le whichtends to rotate the wheel in the direction indicated by the arrow in Fig. 1. `We provide nea-fis cooperating with the wheel which ops topermit the weight to descend, and

me t ie weight descends it produces a ln other Cooperating with thesestops we provide` ay detent-mechanism which is controlled trom adistance preferably by an electric circuit or circuits whichmay beclosed by a push tent-mechanism is coperating with the stop ythedepending arm19 toward the left.

swinging movement would eventually swing 15 to detain the wheel 10 in aposition Vto maintain a switch in its open position.

Coperating with the stop 15 we provide a detent 17 having artoe 18 andadepending arm 19, both rigidlyattached to a4 pivot or stub-shaft 20, sothat. the detent is freely movable. A similar detent, but ina reverseposition is provided opposite tothe detent 17, that is to say, its toe21 projects toward the left instead of toward the right, and this toe21'is in the path of the stop 16.

Associated'with each detent we provide a coil-spring 22, and thesesprings tend'to hold the detents Aprojecting into the paths of the stopsl15 and 16. VVln the operation of the device, when the stop 15 comesagainst the toe 18, it rocks the Vpivot 2Oy and swings This the detentaway Vand cause it to Withdraw from the path of the stop which wouldper- `mit the stop to pass, but such a complete Vmovement 1s preventedby means of a 'trigger 23 which has a pawl 24 to engage a notch in thelower end ofl the arm 19. This trigger 23 is pivoted at 25 and weprovide lelectrical means 'for controlling it to disengage it whendesired. For this pury pose, we prefer to provide an electro-magnet inthe form of a double solenoid 26 having a dou-ble core 27 pivotallyVattached at 28 to the lower end'of the trigger. The coils of thesolenoid'26 are connected in an electric c1rcu1t passing throughconductors 29a and 29'), andwhen this circuit is closed at a remotepoint by'meansl of a switch or pushbutton, the core 27 is attracted andthe trigger 23 is rocked in a clockwise direction about the pivot25.`Fig. 2 'shows therelation of the parts at such a time,rand indicatesthe manner in which the motive force of the weight 14 willoperaterthrough the stop 15 to push the toe 18 out otits path Vso as topermit the stop to pass.

tion of the wheel 10 will continue until theV substantiallydiametrically opposite stop 16 comes against theV toe 21 of the righthand detent, whereupon this detent will berocked in an anti-clockwisedirection until the lower end of this detent arm 30 comes against theend of a` pawl 31, similar to the pawl 24 and formingy a part of theright hand trigger 32. Y

Between the arms 19 and 30, we provide means such asa bar 33 `forlimiting the movement of theV detents by their springs.

TheV rota- Y The triggerV 32 is controlled by a solenoid 34 similar tothe solenoid 26, which is enervwill now be briefly stated In theposition shown in Fig. 1, the actionV of the weight 14 tends to rotatethe wheel 10 in theY directionindicated by the arrow, that is to say,the weight holds the stop 15 against the'toe 18 of the' detent 17.However, the-detent cannot swing out of the way to permit the stop toVpass onv account of the pawl 24 ofthe trigger 23 g however, when it isdesired to close* the switch 7, this is accomplished simply by closingthe circuit Vthrough the conductors29a and 29b and the Vsolenoid 26,whereupon the solenoid rotates or rocks the trigger 23 in a clockwisedirection, thereby disengaging the p'awl 24 from The triggers 23 and'32are Vpref- I the arm 19. This permits the'arm to swing towardthe left,(see Fig. 2),.therebypermitting the stop 15 to pass. Thewheel then Yrotates through a half-revolution, that isto say, it rotates until itsrotation is arrested by the stop16 striking the toe 21 of the' righthand detent. Vhen this occurs, the shock of the contact is takenupsomewhat by the corresponding detent spring 22 which becomes extendedasV the arm 30 swings toward Vthe right until it engages the end of thepawl 31. VThis will hold the wheel 1() in a position to maintain theswitchclosed, Vand the switch will vremain closed untilgthe elevatedpoint.

Y It will be observed that the mechanism ofV this apparatus is verysimple and' not likely 4 to get out of order. It is also evident thatVin the present instance the electric current is not employed torprovidethe motive force for actuating the switch, but simply conp trols themotive force which opens and closes the switch at the will of theoperator.

It is understood that the embodiment ofl the invention described hereinis only one of the many embodiments our invention mayvr takel and we donot wishV to be limited in the practice of our invention nor in our laoVclaims, to the particular embodiment set forth. f
